This one is in the same space as Seamless.AI, Clearbit, Hunter and others, i.e. it's for prospecting. It has an interesting twist which is that you can search for people based on triggers such as "person just started new job with title X" which can help you find people at just the right time. It does not only prospecting but also integrates with Gmail and lets you send to the prospects you find using templates you can save.
